Etymology
The modern English word 'cloud' originates from the Old English 'clūd', which meant 'mass of rock, hill'. This sense evolved in Middle English to refer to a mass of cloud in the sky, likely due to the visual similarity between a cumulus cloud and a distant hill or rock formation. The semantic shift from a solid, earthly mass to a vaporous, celestial one is a classic example of metaphorical extension. The word's ultimate origin is uncertain but is likely from a Proto-Germanic root related to clumps or masses.
Analysis
The word 'cloud' is a simplex word of Old English origin. It cannot be meaningfully segmented into smaller morphemes within its modern English spelling.
Examples
